Abstract (en)
This application provides a sequence-based signal processing method, a communications device, and a communications system. A sequence meeting a requirement for sending a signal by using a PUCCH is determined. The sequence is a sequence {f<sub>n</sub>} consisting of 12 elements,f<sub>n</sub>represents an element in the sequence {f<sub>n</sub>}, and the determined sequence {f<sub>n</sub>} is a sequence meeting a preset condition. Then, the 12 elements in the sequence {f<sub>n</sub>} are respectively mapped to 12 subcarriers, to generate a first signal, and the first signal is sent. By using the determined sequence, when the signal is sent by using the PUCCH, a low correlation between sequences can be maintained, and a relatively small PAPR value and a relatively small CM value can be maintained. Therefore, a requirement of a communication application environment in which the signal is sent by using the PUCCH is met.
